WAVETEK 4920 Alternating Voltage Measurement Standard

The Wavetek 4920 Alternating Voltage Measurement Standard is designed to replace the traditional AC/DC Thermal Transfer Standard in high-accuracy AC measurement applications. Fully traceable measurements can be made with uncertainties equal to or better than all but the most specialized standards with the speed, ease of use, and convenience of a single, programmable, intelligent device. AC Voltage; Ranges: 3 mV to 1000 V in 3, 10, 30 sequence. Resolution: 100 nV, 71/2 digits. Operating Range: From 30% to 110% of Nominal Range Value. Remote Programming: IEEE-488.2. Options; 10: 3 mV to 100 mV Ranges. 50: Wideband Module to 50 MHz.

Carrier Wave (CW)
Carrier Wave or Continuous Wave is a sinusoidal signal without modulation.

A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency, i.e. if the fundamental frequency is f, the harmonics have frequencies 2f, 3f, 4f, . . . etc.

Noise Floor
Noise floor is the measure of the signal created from the sum of all the noise sources and unwanted signals within a measurement system.

Ripple is the small unwanted residual periodic variation of the direct current (dc) output
